    250 Production Cup wheels

    The rules state to use OEM wheels, but I also see guys running wider tire widths, like a 150/60 rear (130 is stock 250). Are the stock wheels being widened at all for the wider tires? Or is that not permitted and the OEM wheels must remain stock?

    OEM wheels must remain stock

    Those riders are experimenting ( some successfully) with different tire sizes on the unmodified stock wheels.
